high milage lifters?
I finally bought the ms3 cam package, I currently have 120k miles on the car. I also bought ls6 ported oil pump, ls2 timing chain. My question to you guys is it a good idea to replace the lifters as well?

It's not a bad idea but it is a decent amount of extra work on top of a cam swap. Chances are if you don't replace them they will be fine but it's nice to put in new lifters to replace ones with that kind of mileage. If you are thinking you might do heads relatively quickly down the road, this would be a good excuse to do so!

With an MS3 am I would not put that cam in unless I would change the lifters, springs, rods. Seriously you have 120K miles on your stock lifters, who have been working with your stock cam.

if you want that piece of mind then get them. thats alot of miles for stockers to handle and now a big aftermarket cam. like mentioned above, its more work but you know they won't fail if they are replaced. I don't believe the stock lifters are made to handle 6300-6400 rpms either???

Check you springs every 5K to 10K miles if you have a very aggressive cam, aggressive lobes and a high lifts. In my opinion and its mine only .615 lift and higher.

Its not the fact of the lifters not being able to handle the camshaft, its they wont like the necessary spring pressure that the new valve springs will be giving.
If it was my car, theres no way in hell I would stick any cam larger than maybe a 224 with that mileage.
My 2 cents.
